Abstract (en)
[origin: WO9938043A1] A radiation-curable, cross-linked ribbon matrix material is suitable for covering an array of coated optical glass fibers. The matrix material contains at least one radiation-curable oligomer or monomer, and at least one chromophoric indicator selected so as to be susceptible to destruction of its chromophoric characteristic upon exposure to radiation and present in an amount which becomes substantially colorless when exposed to a level of radiation sufficient to cure the radiation-curable matrix material, wherein the at least one chromophoric indicator has a color that is distinguishable from a base color of the radiation-curable, optical glass fiber coating composition in cured form. A cable structure and a telecommunications system are also described.
